SOLIMIDE®

Polyimide Foam

SOLIMIDE Foams

Lightweight, Flexible, Thermal and Acoustic Insulating Materials

for Use Where Fire Resistance, Extreme Temperatures or

Weight Savings Are Critical Considerations

…such as Aircraft!

§ SOLIMIDE Foam is supplied by Evonik Foams, Formerly Imi-Tech / Inspec Foams, subsidiary of Evonik Industries

§ Developed in conjunction with US NASA following APOLLO fire that resulted in three astronaut deaths

§ Possesses unrivalled advantages over traditional insulating materials

§ The thermal/acoustic insulation product of choice for solving tough problems aboard marine vessels, aircraft, aerospace and in industry worldwide

Background

Chemistry

§ Polymer with predominantly imide linkages formed during polymerization

§ High glass transition temperature [235°C]

§ Good solvent/chemistry stability

Key Characteristics

§ Open cell foam, low weight [5 to 9 kg/m3]

§ Temperature stability [cryogenic to 300°C]

§ Low off-gassing

§ Flexible, semi-rigid, compression recovery

§ Heat/Pressure formable to some degree

Aircraft Benefits•Low weight with good thermal

and acoustic insulating properties

•Excellent fire resistance –passes FAR 25.856 (a)

•Virtually no smoke or toxic gas emission

•Formaldehyde and fiber free

•Rigid, self-supporting foam; fewer fasteners for lower weight, faster installation and inspection

•Proven long term performance (retains properties, shape)

Advantage: Low Weight

• Weight Savings -- Densities from 5 to 32 Kg/m3

• Additional Weight Savings with Installation –fewer fasteners required

Advantage: Acoustics

Open Cell Structure Provides Excellent Sound Absorption Performance at Frequencies From 500 to 2000 Cycles Per Second.

• Excellent Acoustic and Non-burning Combination

• Good Acoustic Absorption to Weight Ratio

• No Fibers to Release

Advantage: Thermal Control

Effective Thermal Insulation on a Per Unit-weight Basis

• Continuous use to 300°C

• Retains thickness and thermal resistance – even in hot and humid environments

• No phenol-formaldehyde binder to

break down400°C

80°C

Over 300°C Temperature Reduction With 25 mm Thick SOLIMIDE Foam Insulation

Advantage: Fire Resistance, Smoke

Inherently Fire Resistant – Will Not Support Combustion in Air

• Nearly Zero Flame Propagation – FAR25.856a

• Typically Exceeds Fire Regulations

• Numerous Test Results Available

• NBS Smoke Chamber

• OSU Heat Release

• Boeing and Airbus Smoke/Toxicity tests

Emits Virtually No Smoke or Incapacitating Gases

When Exposed to Open Flame

Advantage: Formaldehyde and Fiber-Free

Negligible Outgassing at Room Temperature / Minimal Outgassing at Elevated Temperatures

• Minimal Volatile Compounds Released

• No Odors for Consumer Products

• No “Burn In” Requirement or binder to burn out

• No respirable fibers

• No loss of thickness or sagging in hot, humid environments

• No breakdown or disintegration

Advantage: Easy Installation

• Faster installation with fewer installers

• Fewer Fasteners – reduced weight

• Wrap Around Structures

Self-supporting, but flexible –easy to handle and install

Benefits reported:

• 300 lb. weight reduction (batting only)

• 60% reduction in blanket manufacturing time

• 80% reduction in blanket installation time

(1600 fasteners eliminated from FG design)

• 95% reduction in inspection time

• Moisture mitigation -- elimination of cover film penetrations

• Retention of blanket integrity

Case Study – Qantas Experience

In the early 1990’s, Qantas replaced fiber glass in the bilge areas of their 747 fleet.

Advantage: Life-Cycle Performance

• In 2007, Qantas sent a 10-year old insulation blanket to Boeing for evaluation – it was in great shape!

• Fiber glass blankets disintegrate with moisture – more replacements required during inspection

• Fewer fasteners to begin with means fewer fasteners during inspections

SOLIMIDE Foam maintains integrity and thicknessin hot, humid environments

In the 1990’s:

Alaska Airlines In-Service Study:

• A sandwich configuration FG/Foam/FG was installed and flown for a year

• PI Foam retained 90% of thickness, FG only 50%

• PI Foam maintained coverage area, FG sagged

System Design, 737 Factory Installation:

• Blankets fabricated for factory installation trial – two frame bays, all fuselage above floor

• Blankets installed quickly with minimal fasteners –installers impressed with simplicity and speed
